To all whom it may concern:

Be it known that I, An :LPH W. MANZ, citizen of the United States,residing at. Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Motor-Starters, .ofwhich the following is a specification. f

My invention relates to starting devices for explosive engines and itschief objects are to provide means for preventing a reverse movement ofthe engine shaft when a for wardimpulse has been given thereto by theparts secured b operation of the starting mechanism; to provide meansfor'automatically controlling the compression release cock when thestarting device is. manually operated, and to furnish means forholdingthe operative pawls out of engagement with the cooperatin parts when theactuating lever is in its initia position.

I accomplish the above and-other minor objects by means of the mechanismillustratedin the accompanying drawing which forms a part of thisspecification and in which- I Figure 1 is a side elevation ofa motorstarting device attached to the chassis or framework of a motor vehicle3 Fig- 2 is a rear elevation; Fig. 3 is aside view of the reci rocatinglever and attachments showing t eir relation to the ratchet Wheel whensaid lever is in its'initial position.

Referring to drawing, the numeral 4 indi cates the frame-of amotorcar-to which a plate 5 is secured by bolts or screws 6. Proa jectin fromthe center of said plate and forme integral therewith is a sleeve 7having a bore 8 which registers with the engine shaft. The said plateand sleeve are formed in two bolts 7 a to facilitate assemb ing when t'e shaft passes through the frame. From near'the free end of said sleeve7 a fixed arm 9 projects at an angle and car- 'ries a dog 10 pivotedthereto. at 11, and

The lever .14 is held In itsinitial position, as

. certain constructions. Thejusnal-fly wheel but'hasno connec-' pershown in Fig. 3, by means of a tension spring 18. A cross bar 19 is'secured to the lever-14 near its upper end and is adapted to swingor'rock on a center 20. Below theat-. tachmefnt of the pawl 15 a bellcrank lever. 21 is secured to the lever 14 byv a pivot pin 22. One endof said bell-crank lever is attached to the pawl 15 by a shortlink 23,and tothe other end is attached a flexible metal cord 24 which forms aconnection with-one end of the said cross bar .19. To the opposite endof said bar 19 is secured a traction rope or cable 25which may becarried to any desired location so as to be within convenient-reach o'fthe operator.

A projection 26 extends rearwardly from the lever 14 its rear face 27being inclined and adapted to engage the said dog' 10 when the lever 14is retracted by the-spring 18"to itsinitial position thus raising thedog out of en-.

gagement with the said ratchet wheel 12. When thus raised the point ofthediogwill be received into a notch 29 and thus ke'pt clear of theratchet teeth. Thesa'id ratchet wheel 12 and its collar 30 are formed intwo parts united by bolts 31 thus permitting the ready attachmentofsaidwheel to the shaft 13 with: out requiring the latter to bedismantled for that purpose which would be necessary in 32 is carried bythe shaft tion with my device.

A ulley 33 adapted to receive the tension spring 18 for the purpose ofchanging its direction-is supported on a bracket 34 secured to the body4*.

Attached to the said lever is a short'spring 18 is secured atits other endi37 to any convenient tension spring and release cock is soadjusted The spring 18 after passing over this pulley is'continned inadown-ward ,place below. -This connection-between the as to cause thelatter tobe'openedwhen the spring is extended by the operation of. the

and permitting easy action by allowing some of the compression to.escape from thecyb inder.

The operation oi the device as follows:

With the. mechanism in the initial position shown in Fig 3, traction ismade; manually ver 21 and connecting cord 24 to the driving pawl 15which will be thus extended until it 5 is in engagement with the ratchetwheel 12.,

Further traction upon said cable will carry the main lever 14 to theposition shown in-.

Fig. 1, thus. permitting the dog to engage the teeth of the ratchetWheel. Continuing the pull upon the cable will carry the. main leverover its arc of movement and the pawl will turnthe'ratchet wheel andengine shaft upon whi'chit is mounted at the same.
